Seems that the actual rumor was about the SRD:
https://comicbook.com/gaming/news/dungeons-dragons-open-game-license-srd-one-dnd/ "The YouTuber Indestructoboy claimed that Wizards of the Coast would not create a new System Reference Document for One D&D, the codename for the upcoming new edition of Dungeons & Dragons.

This would prevent publishers from making material specifically for One D&D, although they could still use the existing 5th Edition System Reference Document to publish material 5E material that could be "backwards compatible" with One D&D. While not creating a new System Reference Document for One D&D wouldn't snuff out third-party material, it would certainly discourage publishing or force publishers to turn to the DMs Guild, a digital marketplace that uses a separate license in exchange for Wizards of the Coast and DriveThruRPG (the manager of the DMs Guild) taking a 50% cut. We'll note that Wizards of the Coast previously turned away from the Open Game License for the release of 4th Edition D&D, with a more restrictive Game System License used instead.
ComicBook.com reached out to Wizards of the Coast about whether they planned to update the Open Game License and System Reference Document. Wizards of the Coast responded with the following statement: "We will continue to support the thousands of creators making third-party D&D content with the release of One D&D in 2024. While it is certain our Open Game License (OGL) will continue to evolve, just as it has since its inception, we're too early in the development of One D&D to give more specifics on the OGL or System Reference Document (SRD) at this time."
WotC cannot undo the existing 5.1 5e OGL. All they can really do is not update it, which will make it harder for people to make D&Done compatible content independent of the new OneSRD.
Depending on how tight WotC is with their SRD for D&Done will be the kicker...
Will they only allow 3pp to use the SRD if they can make content for the one VTT?
That is the big question.
This also presumes WotC has hired programmers worth a damn.
Well, if it’s anything like the quality for 4E, they’re hosed.
...
Wotc/Hasbro has hired people with a solid track record of success in digital gaming.
I think many are underestimating how serious WotC is about making the one VTT successful
for them.
